--- Comment #1 from Carlos Garnacho <carlosg at gnome.org> ---
As far as I could see, this is more a client-side vs wm decorations, mutter
fully ellipsizes the title, whereas gtk+'s headerbar label has a larger minimal
size. I guess it would be nice to be consistent there, although I guess there
won't be many places where the minimal width of the headerbar is larger than
the content's.

I saw some pixman warnings though on csd when running the testcase, both on
wayland and with GTK_CSD=1 on x11.
